This is not a method for magicians, that's a "system" for readers. If you think you can spot Cancers
by their long hands or Leos because they are the heart of the party, that might be for you. Might.
If you want to sound like you are using signs, that's too short even for an introductory course not
enough matter on what signs are supposed to be and behave like. And if you want a method to know for
sure someone's sign, well, that's not it either.
